P3416 is the universal OBD-II code for Cylinder 2 Exhaust Valve Control Circuit High. Cylinder 2 simply indicates that the issue is probably taking place in engine cylinder number 2.
Most newer vehicles with eight or more cylinders are equipped with a feature which allows half of the engine cylinders to shut down when they’re not needed – such as times of light load operating conditions. Various components – such as the mass airflow sensor (MAF) – send data to the ECM (engine control module) – informing it of the operating conditions so that it can signal cylinders to turn on and off depending upon when they are needed.
The data sent to the ECM from the various sensors is supposed to be within a certain range, measured as voltage. When this signal is out of the scope of what it should be, a fault code will set – in this case P3416 – alerting you to the fact that something is not right with the cylinder 2 exhaust valve.
Automatic cylinder deactivation can have a number of potential causes, including:
While it is possible for the ECM to be at fault in a problem like this, that is almost never the case.
The Service Engine Soon lamp may illuminate, and the vehicle will not be able to switch over to the lower power mode, such as V4. There could be vibrations while driving, and a potential loss of fuel efficiency over the long run.
Steps a technician may take to diagnose this fault code include:
The most common error people make when diagnosing this code is to replace system components without first carrying out all recommended steps in the diagnostic protocol. Oil blockages in particular must not be overlooked – these can frequently cause oil pressure issues which may lead to this fault code setting.
While the vehicle will still run even with this code active, if the problem isn’t addressed in a timely manner the engine could be put under excess strain, and fuel efficiency will suffer. The best thing is to have a qualified professional assess the situation as soon as you can get your vehicle into the shop.
Possible repairs for a cylinder 2 deactivation malfunction may include:
A cylinder 2 deactivation or exhaust valve problem could involve a number of complex possible solutions. A qualified automotive technician has the appropriate tools to quickly and efficiently diagnose and repair the source of the problem. Pinpointing an issue with an engine cylinder can take the home mechanic a considerable amount of time and expense. If your vehicle is setting the P3416 code, it may be best to have it assessed by a professional technician.
